No because it's completely unrelated. The amount of shared memory doesn't vary while the system is running and it gets removed once you restart postgres. So it can't cause you to run out of memory (unless you allocated a truly huge amount of memory that way, but that's bad for other reasons). At worst it's gets stuffed into swap until you next start postgres. Have a nice day, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > Patent. n.
